ANTIRAT'ILING DEVICE.

Specification of Letters Patent.

Patented Jan. 9, 1917.

To all whom it may concern:

Be it known that f, JOHN Kinny, Jr, a citizen of the United States,residing at Dayton, county of Montgomery, and State of Ohio, haveinvented a certain new and useful improvement in antirattling devicesfor use more particularly in connection with window-sashes inrailway-cars and other moving vehicles, and of which the following is afull, clear, and exact description.

The invention relates to the .class of window devices in which springactuated rollers are employed to prevent rattling of sashes when looselyfitted in their guideways, by forcing the sashes closely against theguide-strips at one side thereof, thereby preventing rattling of thesashes and excluding dust, cold air, etc.

The principal object of my invention is to produce an antirattlingdevice of its character which shall combine maximum efficiency withminimum cost of production, and it consists in the combination andconstruction of parts herewith described and claimed at the end of thisspecification, in which reference is had to the accompanying drawingsand to the reference numerals marked thereon which indicatecorresponding parts in all the figures thereof.

In the said drawings, Figure 1 represents a broken perspective view ofone of the upper corners of a car sash in operative position in itsframe work and showing my improved device mounted thereon. Fig. 2 is arear perspective view of the assembled device detached from the sash.Fig. 3 view of one of the rollers in position in its supporting frame.Fig. 1 is a perspective view of one of the roller-frames which carry therollers, the roller being removed therefrom. Fig. 5 represents a crosssection through line X X of Fig. 2, and

Fig. 6 is an end view of Fig. 2.

Referring to the said drawings, 1 designates a vertical rail and 2 thetop, horizontal, rail of a window sash, 3 represents the outerguide-strip, 4: the inner guide-strip and 5 the post forming one side ofthe window opening, the post 5 together with the guide-strips 3 and 4forming a channel or guideway for the sash.

6 represents aforwardly inclined springactuated roller-frame comprisinga single piece of spring wire formed with what I is a plan will describeas, parallel sections 7, spaced apart at 8 to provide a receptacle for aroller 9, which spacing is accomplished by a transverse section 10, acoil 11 being as more clearly shown in Fig. 2. In each of the parallelsections 7 there is also formed a loop 12 to receive the ends of pintles13,

which for convenience in assembling I prefer to make of tubular form,upon which the roller, 9, rotates, the ends of the pintles beingsoldered, or riveted, or both, to the parallel sections 7.

14 represents 'a base-plate which is mortised into the edgeof thevertical sash rail and secured thereto by means of screws which passthrough holes 15.

to and between the inner ends of these facemembers the rollers operatein a suitable recess 17, cut in the sash.

On the under side of each of the facemembers 16, and preferably formedintegral therewith, there is provided a small stirrup 18 whose functionis to receive the free ends of the wire frame 6 which are securedtherein and to the face-member by soldering, and when thus permanentlyattached the forward movement of the roller is limited by theface-member, against the under side of which the wire frame bears whenthe device is detached from the sash, as best shown in Fig. 2. When thedevice is mounted on a sash and the latter is in operative position inits guide-ways the forward movement of the roller is limited by theguide-strip against which it is forced by the spring action of the wireframe and which normally is forward, as more clearly shown in Fig. 1.

By referring to the drawings in connection with the foregoingdescription of my invention it will be obvious that while a pair ofrollers are shown and described the device is equally well adapted tothe use of a single roller and supporting frame if and when one isdeemed to be sufiicient, in which case but one face-member need beemployed and the base-plate may be correspondingly shortened; that thedevice may be applied to either the inner or outer side of the ver- Thebaseplate 1 1 1s provided at each end with facemembers 16 disposed atright angles theretical sash rail and at either or both edges and at anydesired location between the top and bottom rails of the sash, or toeither the inner or outer guide-strip, in which latter case the rollerswould bear against the adjacent face side of the sash. It will also beapparent that the device combines the features of' substantiability,efficiency and minimum cost of production and that the details ofconstruction may be departed from without departing from the scope of myinvention.

I claim 1. In an anti-rattling device, the combination of a face-member,a roller-frame secured at one end thereof to the face-member andconsisting of a single piece of spring wire formed to constitute twoparallel side members and a transverse member located approximatelymidway of the ends of the frame and by which the side members are spacedapart to receive a roller, a loop formed in each of the side members atthe free ends thereof, a pintle whose ends engage said loops and aresecured therein to the side members, and a roller mounted on the pintleand adapted to revolve thereon between the side members forward of thetransverse member.

2. In an anti-rattling device, the combina tion of a face-member, aroller-frame secured at one end thereof to the face-mem ber andconsisting of a single piece of spring wire formed to constitute twoparallel side members and a transverse member located approximatelymidway of the ends of the frame and by which the side members are spacedapart to receive a roller, a loop formed in each of the side members atthe free ends thereof, a pintle whose ends engage said loops, and aresecured therein to the side members, a roller mounted on the pintle andadapted to revolve thereon between the side members forward of thetransverse member, a coil formed in each side member to impel a forwardmovement to the frame, and means for limiting said movement.

3. A new article of manufacture comprising a roller-frame for ananti-rattling de vice consisting of a single piece of spring wire formedto constitute two parallel side members and a transverse member locatedapproximately midway of the ends of the frame and by which the sidemembers are a spaced apart to receive a roller, each of said sidemembers having a loop adapted to receive a pintle for supporting aroller and a coil to impel aforward spring action to the frame.
